Mundorf ferrit core coil

In non-impregnated coils, vibration occurs as a result of the current flowing through the coil.
The microphonic effect, i.e. the conversion of mechanical into electric oscillations, adds these
oscillations back to the original signal as additional information. In this way, details of the
original signal are overlaid and rendered unrecognisable. The music loses spatial quality and
transparency. This process is prevented by

vacuum impregnation
